LEGO Sets for Ages 1–3
Duplo and LEGO toddler sets are designed specifically for children aged 1–3. The large bricks are impossible to swallow, easy to grip, and frustration-free to assemble. Builds are simple enough to complete in minutes and rebuild freely.
Buying Tips for Ages 1–3
Look for the 'LEGO DUPLO' or 'LEGO Classic' branding — regular LEGO has small parts unsuitable for under 3.
Builds at this stage are as much about the activity as the finished model — rebuilding repeatedly is normal and good.
Choose sets with bright, single-colour bricks rather than complex multi-step builds.
